Config and Boot ​

bash
# config

# boot 
cat > /etc/systemd/system/tikv.service << "EOF"
...

systemctl daemon-reload
systemctl start tikv.service
systemctl enable tikv.service

Verify ​

bash
# verify by pd-ctl
./bin/pd-ctl store -u http://127.0.0.1:2379

# verify by python-sdk client
# install client
pip3 install -i https://test.pypi.org/simple/ tikv-client
# python sdk test
from tikv_client import RawClient
client = RawClient.connect("127.0.0.1:2379")
client.put(b'foo', b'bar')
print(client.get(b'foo')) # b'bar'
client.put(b'foo', b'baz')
print(client.get(b'foo')) # b'baz'
